Abstract
The nickel promoted tandem cyclization-quenching of tethered aminobrom odienes has been extended to the synthesis of 2,3,4-trisubstituted pyr rolidines. By a judicious choice of substituents on the starting amino halodiene, the diastereoselectivity of the process can be efficiently controlled. When a chiral auxiliary on the nitrogen atom is used, enan tiomerically enriched pyrrolidines can be obtained after removal of th e auxiliary. (C) 1998 Elsevier Science Ltd. All rights reserved.
